Step-by-step explanation:
The Minnesota Multiphasic Personality Inventory (MMPI) is a self-report inventory strategy used widely in psychological assessment. This test features a series of true/false questions designed to assess personality traits and psychological disorders. The MMPI's development involved a strategy that distinguishes between "normal" and "abnormal" psychological conditions by comparing individuals' responses to a broad range of questions with those of a standardized sample, which historically included Minnesota farmers and psychiatric patients. The MMPI helps in creating a clinical profile based on various scales that measure different aspects of psychological functioning.
